“A man a women had a son, they decided to move to greener fields
, and eventually found a place where it was very beautiful
there a man rented a house to them. They lived well until one day
during the night a wolf went into their house and stole their son.
They wept, but eventually recovered and tried again, giving birth to a second son.
Soon after the child was born the renter visited them and congratulated
them. Bought were happy, until one day the wolf returned and stole their second
child.
Devastated they changed place, left that house and never returned, eventually had a third
child and although they weren’t in that green field they were safe has the wolf never returned.”

This is my remembering of a old story of writer Ayaan Hirsi Ali, that her
grandmother told her during her childhood. The lesson here is that greener
fields aren’t always the safest. The renter was the wolf. If you buy her
biography it will give you a better read.
